Cosmic targets for Webb Telescope’s first images announced

Below is the list of cosmic objects that Webb targeted for these first observations, which will be released in a live broadcast beginning at 16:30 CEST Tuesday, July 12. Each image will simultaneously be made available on social media as well as on partner agency’s websites. ESA will host the images here.

These listed targets below represent the first wave of full-colour scientific images and spectra the observatory has gathered, and the official beginning of Webb’s general science operations. They were selected by an international committee of representatives from NASA, ESA, CSA, and the Space Telescope Science Institute.

• Carina Nebula
  The Carina Nebula is one of the largest and brightest nebulae in the sky, located approximately 7,600 light-years away in the southern constellation Carina. Nebulae are stellar nurseries where stars form. The Carina Nebula is home to many massive stars, several times larger than the Sun.

• WASP-96b (spectrum)
  WASP-96b is a giant planet outside our Solar System, composed mainly of gas. The planet, located nearly 1,150 light-years from Earth, orbits its star every 3.4 days. It has about half the mass of Jupiter, and its discovery was announced in 2014.

• Southern Ring Nebula
  The Southern Ring, or “Eight-Burst” nebula, is a planetary nebula – an expanding cloud of gas, surrounding a dying star. It is nearly half a light-year in diameter and is located approximately 2,000 light years away from Earth.

• Stephan’s Quintet
   About 290 million light-years away, Stephan’s Quintet is located in the constellation Pegasus. It is notable for being the first compact galaxy group ever discovered. Four of the five galaxies within the quintet are locked in a cosmic dance of repeated close encounters. 

• SMACS 0723
   Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a deep field view into both the extremely distant and intrinsically faint galaxy populations.

The release of these first images marks the official beginning of Webb’s science operations, which will continue to explore the mission’s key science themes. Teams have already applied through a competitive process for time to use the telescope, in what astronomers call its first “cycle,” or first year of observations.

About Webb

The Webb telescope lifted off on an Ariane 5 rocket from Europe’s Spaceport in French Guiana on 25 December 2021 on its exciting mission to unlock the secrets of the Universe. Webb, a partnership between NASA, ESA and the Canadian Space Agency (CSA), is designed to answer outstanding questions about the Universe and to make breakthrough discoveries in all fields of astronomy. The major contributions of ESA to the mission are: the NIRSpec instrument; 50% of the MIRI instrument; the provision of the launch services; and personnel to support science operations. In return for these contributions, European scientists will get a minimum share of 15% of the total observing time, like for the NASA/ESA Hubble Space Telescope.
